SPECIFICATION forming Vpart of Letters Patent No. 267,527, dated November 14, 1882. `Application filed November 26, 1881. (No model.)

To all whom it may concern:

Be it known that I, CONRAD HILGENBERG, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Im provementsinType-WritingApparatus; and I do hereby declare that the following is a full, clear, and exact description thereof, reference-being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of my invention is to produce a type-writing apparatus in which, in place of a number of keys that have to be touched for prlnting the several characters, a simple lever will accomplish the change in the type, as well as the printing of the same; and it consists of the devices and combinations of devices as hereinafter described, and pointed out by the claims.

In the accompanying drawings, Figure 1 represents a transverse section of my type-writlng apparatus ;v Fig. 2, a longitudinal vertical section of the same, and Fig. 3 a plan view.

Like letters represent corresponding parts in all the figures.

A denotes a box-frame of any suitable eXterior shape, and consisting of the base c, sides b, and top c. This top c has a circular opening, the surrounding edge of which is graduated, and has imprinted the several characters or fac-similes of the types in the usual succession.

B is a turn-table, having a V-grooved rim, and being guided between a series of rollers, d, that have a V-shaped rim and are pivoted upon columns e, which rise from the base a of the frame. This turn-table B is, besides, supported upon rollersj', which turnl in bifurcated standards g, also secured upon the base c of frame A. Y

C is a lever, which at one end is pivotally connected to one side of turn-table B, is slotted in its middle portion, and has an upwardturned handle at its opposite end.

I) is a vertical stud secured upon the base a of frame A.

E is a lever pivotally supported at about its center in a forked standard, h, upon base a ot' frame A. One end of this lever E is slotted, and the stud D passes through this slot and through the slotted portion of lever C. A sleeve, F, that slides upon the stud D, is interposed between the levers C and E, so as to transmit a downward pressure from lever C to lever E. This sleeve, asvwill be noticed, forms connection between both levers. A ycoiled spring, Gr, is placed around the stud D, between lever E and base a of frame A, for raising the levers again after each depression.

The turn-table B has a series of holes or slots, m, near its periphery, each provided with a tubular casing, i, secured against the bottom face of the turn-table for vertically guiding the several types,j, each type beingv surf rounded by a light coiled spring, k, that will pull it downward. The table B is rotated by the lever C, and a pointer, Z, that is hinged to the under side of the handle of lever C, is to indicate on the graduated face of frame-top c the corresponding type in the turn-table B, that is just above the lever E, which type will be pushed upward by depressing the lever C.

H is the roller that is to carry the paper to be imprinted. This roller is pivoted between two centers in a bow-shaped yoke, I, which has a rack-bar, m, at one end and a plain bar, n, at the opposite end. These bars m and n are guided in slotted posts o, secured upon or against the frame A, and one of these posts carries a pinion,p, which engages with the rack m of yoke I in a manner that the rotation of said pinion p will shift laterally the roller H. A ratchet'wheel mounted upon one end ofthe shaft that carries the pinion p, and a pawl suitably connected with either lever C or E, may be attached to shift the roller H automatically the proper distance in a lateral direction for each letter to be printed, and other devices may be applied for reversing and rotating the roller after each line has been printed, neither of which arrangements I intend to claim in this application. The roller H is placed in such a position relative to lever E that the type raised by said lever will strike it centrally and rectangularly. Inking-rollers q, made of hollow perforated tubes that are covered with felting and filled with ink, are pivoted in said frame at a position where the faces of the types, in passing underneath, will rub against them and will be automatically inked.

What I claim is- In a type-writing apparatus, the combination of the turn-table B, having V-grooved rim IOO and holes eaeh hole being provided with a tubular easing, fi', secured to the bottoni of the turn-table for guiding the types, the vertically1noving typesj, each surrounded by a coiled spring, 7.1, for retraeting the same, the V-sha-ped rollers d, rollers f, lche hand-lever C, pivotally connected with said turn-table, the lever E, pivoted upon the frame in forked standard h, the connecting-piece F, and spring G, all eonstrueted and arranged to operate substantially 1o in the manner set forth.

In testimony that I claim the foregoing as my invention I affix my signature in presence of two Witnesses.

CONRAD IIILGENBERG.
